Watch Your Back With a Reversing Camera

They say necessity is the best inventor. One such invention that came into existence due to a dire necessity is the reversing camera. This is a special video camera that was specifically produced for the purpose of providing drives with a better rear view in order to aid the backing up process.

Reversing cameras go by many different names in the market. They are popularly known as rear view cameras and backup cameras. There are a number of reasons that led to the development of the backup camera. Primarily they function to help the driver. They make it easy to watch out for obstacles that may not be visible through the conventional rear view mirror. They also help to avoid bumping into other cars while parking your car in a tight spots.

Furthermore statistics go to show that young pedestrians face a grave threat from backing up cars across the world. This is especially true with regards to little children. Since their height is small they are often not visible to the backing up driver. As a result many children are injured and some even lose their lives in backing up accidents. The backup camera comes to the deliverance of all those young pedestrians that stand in danger of being run over by a reversing car.

ISO Setting in Digital Cameras

What happens when we select a certain ISO value in our digital camera? What is the best ISO setting for our particular camera? Can we change it light-heartedly or does it deserve a more careful consideration? Read on to learn how we can improve our photographs through the right selection of the ISO setting.

Let me give you the bad news, first. Camera manufactures do not disclose strategic and sensitive information such as what happens internally when the user select a certain ISO value. Anyway, through sound reasoning and a little of reverse engineering we can speculate on it and come to meaningful conclusions. In particular, reverse engineering is best performed on RAW file format, rather than JPEG, because JPEG compression introduces artifacts and algorithms complicating the process.

For starters, we need a definition. Image sensors have a so-called native sensitivity. This is the innate or natural sensitivity of the sensor when compared to a standard film. For instance, if the native sensitivity of a certain sensor is 100 ISO, it means that it gives comparable results to a 100 ISO rated film when both are used at the same aperture and shutter speed. Native sensitivity cannot be changed, because it is inherent to a certain sensor. Therefore, when we change the ISO speed setting, something must occur involving the circuitry serving the photosensitive sensor. More specifically, things play out differently according to whether an ISO greater or lower than the native sensitivity is selected. Let us see the two cases separately.

How to Protect Your DSLR Camera Lens From Dust, Mold and Scratches

If you’re looking for ways to protect your expensive lens investment for your DSLR camera, then you’re on the right place. In this article, I will explore some ways that you can protect your lens from dust, mold and scratches. The first way to protect your lens is to use the included lens hood that comes with your lens when you buy it. The second way is to use a filter that you can screw on the front of the lens. And the final way is just to simply following good procedure of keeping your lens clean after every use and moving it out of harmful environment. By the end of this article, you would have the ability to choose which way is the best way for you to protect your lens given your preference.

The first way that we’ll look at is to use a lens hood. Not all lenses come with a lens hood. The cheapest lens usually don’t come with one. However, if your lens comes with one, you can put it on whenever you are shooting with that lens to protect it from bump and scratches. The advantages of using your lens hood is that it is cheap (because most comes with the lens itself) and convenient. When you are done shooting, just put the lens hood in reverse position and you are good to go. The downside of using a lens hood is that it extends the lens dimension. This is definitely a downside when you are trying to shoot discreetly as people will immediately notice your camera by the size of your lens.

The second way is to use a screw in filter. This is usually the most preferred method of protection that is used by many photographers. A filter is convenient to use because it does not add dimension to the lens and it saves you from removing it every time after use. A filter will not become a problem when you are trying to shoot discreetly. There are some downside of using filters though. A good filter can be expensive to buy and it decreases image sharpness. If you try to buy a less expensive filter, then it will decrease image sharpness more. Make sure you spend enough money to get a good filter as because your image quality won’t suffer as much.

Innovations in 35mm SLR Camera Design: 1980 to 2000

In 1980, the Nikon F3 was the first 35mm SLR with a viewfinder liquid crystal digital data display (LCD). This showed little more than shutter speed information, but it started a design trend that virtually all SLRs adopted in some form.

German company Rolleiflex was the first of several companies (including Yashica’s Samurai, and Ricoh’s Mirai later in the 1980s) that attempted – and failed – to introduce an alternative camera shape with their now forgotten SL 2000 F. Let’s just say it didn’t prove popular. In the same year (1981), Pentax marketed the ME F: a heavily modified ME Super that was the first 35mm SLR with built-in auto-focus. This used a passive contrast detection system, which worked poorly, and was a commercial flop.

Sigma was more successful, and produced a 21-35mm f/3.5-4 zoom lens: the first super-wide angle zoom lens for SLRs. I’m not going attempt to address the technicalities, other than to say that computer-aided design made possible something previously thought to be impossible.

Learn More Digital Photography Tips Now

With the advent of digital technology, photography has finally come out of its ivory tower and is now the prerogative of even the most inexperienced amateur. While this in no way means that you are exempt from paying attention to all the intricacies, which range from light conditions to color themes, it also does mean that you can afford to make a few mistakes while capturing the image, without having to worry about all the dire consequences if it doesn’t end up like it’s supposed to. And here’s where you need to pay attention to not just choosing the best version of editing software, but also to mastering the basics for it is only when you are a natural with these key functions that you will be able to move on to the more complicated procedures which you will eventually graduate to, in the course of your foray into the world of editing.

Even as you set out to rework your photographs, stop a moment to save a copy of the original image in a folder you can easily access if need be. This is because if your efforts at editing yield results that are contrary to what you set out to achieve, you can simply revert to the original you have and begin all over again. Once you open your image in your photo-editor, you will find an option which says ‘Save As’ which you need to click on to save the original and get to work on the copy you’ve created. And once you set forth, don’t restrict yourself with the fear of having to plod through the entire process if you create an effect you aren’t particularly fond of. You can eliminate the unwanted change with the ‘Undo’ option that your software will provide you with, and if you’re one of the lucky few who has the more sophisticated versions, you can even avail of the ‘Multiple Undo’ option. This remarkable feature lets you stick with only the changes you like while deleting the unwanted ones.

Being a pro when it comes to maneuvering around the image is vital to how quick and easy your editing process is. A popular navigating tool is the ‘Hand Tool’ or the ‘Pan Tool’ which allows you to work your way up and down the image, without making any inadvertent changes to it. You can also choose the zoom options to be more accurate in your editing process which are represented by the ‘Magnifying Glass Tool’. This tool displays a plus sign as you draw in to make the necessary changes and the negative sign as you zoom out to assess the effect of your changes to the overall image. While most types of software let you left click on the image to zoom in or out, many versions also let you right click on the image to proceed in set increments.
